Quite often you end up with at least 2 different logical possibilities. When this happens you cannot determine which is reality. So you have to assume BOTH are wrong... one perceived one possible. Then you make a prediction which could only occur if one was correct and not the other. Even if this is for the one you deem possible but incorrect. In fact it is best to develop 2 predictions if possible. One for each and wait. Later if one pans out then you know your logic is correct or not and can begin to adjust your perceptions to reality. This is a VERY valuable tool in business.
